[Comparison of labour induction with intravenous prostaglandin E2 and intravenous oxytocin (author's transl)].

Based on our results we are able to attribute to the PGE2 a special importance during the beginning of cervical dilatation. A cervical dilatation up to 3 cm is faster achieved by cervical relaxation effect and a direct effect on myometrial tissue independant from exterior parameters. The earlier the cervix has reached such a dilatation, the earlier regular contractions are registered at inductions with PGE2. These contractions are furthermore more effective and led to a shorter induction delivery interval under a minimal physiologic stress. This procedure is combined to a lower intrauterine pressure and shows no negative sideeffects on child and mother.
